I am a Type 2 diabetic. I do not take insulin and know nothing about Type 1. My thoughts are for those with Type 2 and are strictly only suggestions.
There is absolutely no question whatsoever that low carb diets are the only way to " halt" high blood sugars.
I have known and tested this time and time again and fallen off my bike and allowed myself to eat spaghetti, biscuits, sugar etc etc.
Last week I decided enough was enough when my doctor raised my blood pressure pills and I am still on 2 metformin a day, plus a "happy" pill to help me thru the stress of a long drawn out court case. I decided to drop the metformin I took at dinner and only have the one in the morning. I also decided that, knowing low carb was the answer, cut out everything with flour in, including thickened tinned products and fruit. Since taking this stance my blood sugar has not been over 5.8. I have 2 pieces of bread during the day (low GI) and of course bread contains sugar and you cant really help this. Just dont take sugar in your drinks or eat such as ice cream, cake, pastries and biscuits or sweets or anything else which is obviously laden with sugar. Cut out (or just have 1/2 of a medium potato with dinner, (dont have bread as well) and plenty of greens. A normal days menu for me would be
Breakfast (I eat a big breakfast) 2 to 3 tablespoons of ground linseed, (you should get this at any health store, or at most large supermarkets) yes, 1/2 tea spoon sugar, and milk. The linseed I treat as any other morning cereal,(but most cereals are high carb and/or high sugar) then 1/2 slice grain bread, (vogels, burgen and such) 1 poached egg, 1 table spoon tinned or fried tomato, (Some contain sugar) any cooked meat or fish. (tomorrow its mince) and a green, say lettuce or spinach, cream mayo (nil or very low carb) Cup or two or three white tea.
Lunch. 1 piece of bread with cheese and onion plus a salad if you wish, ( or cheese or tinned fish or any other protein, with salad and mayo)
Dinner. Meat or fish ( as much as you want) (after the nuclear accident, I dont eat much fish) heaps of greens with butter in them and a bit of salt. tomato, gravy,( yes, but be sparing as it has thickening, and 1/2 slice bread. Dont be frightened to eat butter, eggs, cheese, cream, meat, fish, in fact any protein you wish, and any greens, or veg. that grows ABOVE the ground, with the exception of onions, fried boiled or raw. which are good for you and OK to have. You can eat sausages and bacon (but not too often) . Dont forget milk contains carbs, especially low fat etc. I have a good deal in tea throughout the day, but wont make a milk drink. I have now lost 3 kg in a week and expect another drop this week. I am not fat, so its not the weight that is causing my high blood sugar its pure and simple eating too many carbs. Lastly, before introducing anything into your diet, check the carbs. Capsicum (or peppers) grow above the ground and I have not checked these. Love to hear from anyone re success at this.
